Struct UserAgentEmulateService

pub struct UserAgentEmulateService<S, P> { /* private fields */ }
Expand description

Service to select a [UserAgentProfile] and inject its info into the input Context.

Note that actual http emulation is done by also ensuring a service such as UserAgentEmulateHttpRequestModifier and UserAgentEmulateHttpConnectModifier is in use within your connector stack. Tls emulation is facilitated by a tls client connector which respects the injected (tls) client profile.

See the implementation ofEasyHttpWebClient for the reference implementation of how one can make use of this profile to emulate a user agent on the tls layer.

Implementations§

§

impl<S, P> UserAgentEmulateService<S, P>

pub fn new(inner: S, provider: P) -> UserAgentEmulateService<S, P>

Create a new UserAgentEmulateService with the given inner service and provider.

Provider is implicitly expected to be a UserAgentProvider.

pub fn optional(self, optional: bool) -> UserAgentEmulateService<S, P>

When no user agent profile was found it will fail the request unless optional is true. In case of the latter the service will do nothing.

pub fn set_optional( &mut self, optional: bool, ) -> &mut UserAgentEmulateService<S, P>

See Self::optional.

pub fn try_auto_detect_user_agent( self, try_auto_detect_user_agent: bool, ) -> UserAgentEmulateService<S, P>

If true, the service will try to auto-detect the user agent from the request, but only in case that info is not yet found in the context.

pub fn set_try_auto_detect_user_agent( &mut self, try_auto_detect_user_agent: bool, ) -> &mut UserAgentEmulateService<S, P>

See Self::try_auto_detect_user_agent.

pub fn input_header_order( self, name: HeaderName, ) -> UserAgentEmulateService<S, P>

Define a header that if present is to contain a CSV header name list, that allows you to define the desired header order for the (extra) headers found in the input (http) request.

Extra meaning any headers not considered a base header and already defined by the (selected) User Agent Profile.

This can be useful because your http client might not respect the header casing and/or order of the headers taken together. Using this metadata allows you to communicate this data through anyway. If however your http client does respect casing and order, or you don’t care about some of it, you might not need it.

pub fn set_input_header_order( &mut self, name: HeaderName, ) -> &mut UserAgentEmulateService<S, P>

See Self::input_header_order.

pub fn select_fallback( self, fb: UserAgentSelectFallback, ) -> UserAgentEmulateService<S, P>

Choose what to do in case no profile could be selected using the regular pre-conditions as specified by the provider.

pub fn set_select_fallback( &mut self, fb: UserAgentSelectFallback, ) -> &mut UserAgentEmulateService<S, P>

See Self::select_fallback.
